An insignificant portion of the population is homosexual. Gays give the number as 10%, most Christians say more like 1 or 2. Gluttony, on the other hand, affects a supermajority of Americans. 60% of us are overweight. There are many more that are gluttonous but lucky enough to have a good metabolism. We seldom eat because we are truly hungry. The portions at any restaurant are vast. Why don't we try making laws against prevalent sins like this, instead of ones only a tiny fraction of us participate in?
you are adding to scripture. Give me the book, chapter and verse that says God calls being overweight sin and calls for a sacrafice or confession of such. Also show me the guidlines that God gives for what constitutes being overweight.
